The Effects of BCAA-Enriched Essential Amino Acid Mixtures and Exercise on the Muscles: A Randomized, Single-Blind, Placebo-Controlled Trial

Background: Protein intake provides the essential amino acids (EAA) neces- sary for promoting muscle protein synthesis. Branched-chain amino acids (BCAA) belonging to the EAA in particular are known to have more potent effects. We developed BCAA-enriched essential amino acids (BEAA®) to im- prove muscle health and performance. Therefore, we aimed at comparing the effects of BEAA® and whey protein intake in combination with exercise on muscle mass and strength in humans. Methods: A randomized,...
